Relatively misleading and useless graphs and statement heading, Ann. (showing total population and percent that are under 18 would have been better, with a graph of total energy use on top)Personally, I long for the days of the 1950s. Before depletion hit, before extreme pollution hit, when the world had half the people or less. When we had a smiling nice guy and a war hero for President. Per capita energy use was much lower. Stratocasters were new. We had our own US culture, and the border patrol rounded up and deported all the illegals. There were no friggin mosques in this country(so few that most didn't know about them--the precursors of over 1300 now, enemy enclaves). Superman was on TV fighting for truth, justice, and the American Way. We made good progress after that first Earth Day in 1970, people started using less power per capita and had fewer kids. Until the effects of immigration hit and stupid economists unduly influenced rose colored glasses wearing Presidents.

The first mosque in America was probably build by Albanian Muslims in 1915 in Maine. By 1919, they had established another mosque in Connecticut. Polish-speaking Tatars build a mosque in Brooklyn, NY in 1926, which is still in use. African American Muslims established the first Mosque in Pittsburgh, PA in 1930. The Lebanese Community of Cedar Rapids, Iowa, opened its first mosque in 1935. The State Street Mosque in New York City was established by Sheikh Dawood Ahmed Faisal in 1955. This mosque represents a special point in the development of the American Muslim community. The Dar-ul-Islam movement began from there

sorry I will interpret what I saw in the graph: when the population increase per year increased, it is either babies or immigration. Being that the second increase (1950-1960 on the graph) roughly matches the "Post–World War II baby boom" and matches a dramatically higher amount of percentage of yearly energy use increases, it shows to me that the need for more energy in a home can be caused by child-rearing activities. Washing machines, water use, packaged foods and dairy products, keeping all parts of the house warm, lights at night, driving kids around... yeah I can see all sorts of increases in energy use.
